We aim to develop advanced methods for determination of coal properties required for optimising gas recovery, scheduling future developments and water management by Queensland Gas Company. We will characterise multiphase flow of gas and water in coal cores by Positron Emission Tomography and flooding experiments. Advancement in knowledge is achieved by using massive data from 4D-imaging to predict evolution of petrophysical properties at in situ condition in different types of coal. This will future proof Australia as the world’s largest exporter of natural gas and will provide significant benefit for the industry in satisfying domestic gas security, maintaining international commitment and addressing environmental concerns.

Selective wellbore coatings to control fines damage in coal seam gas wells. This project aims to develop a completely new approach to control solids production in coal seam gas wellbores using a selective phase-inversion polymer coating. The approach will take advantage of the low permeability of mudrocks to form a protective barrier across clay-rich layers while remaining permeable across the gas-producing coal seams. The production of fine solids is a key technical issue affecting the producti ....Selective wellbore coatings to control fines damage in coal seam gas wells. This project aims to develop a completely new approach to control solids production in coal seam gas wellbores using a selective phase-inversion polymer coating. The approach will take advantage of the low permeability of mudrocks to form a protective barrier across clay-rich layers while remaining permeable across the gas-producing coal seams. The production of fine solids is a key technical issue affecting the productivity of coal seam gas wells in Queensland, and leads to 10-15 days’ production downtime a year. The expected outcomes of the project include fundamental understanding of the solids breakage phenomena, a predictive tool to classify potential solids risks in coal seam gas wells, and a novel rock-selective wellbore coating technology to control solids production. The potential economic impacts from the project are lower gas production costs and improved gas supply security.Read moreRead less

This project aims to assess the viability of potential shale oil and gas reserves, using Nuclear Magnetic Resonance (NMR) core analysis and well logging techniques to characterise shale samples. Shale oil and gas reserves have the potential to provide a rapidly dispatchable energy source, which could play a key role as a transition fuel to renewable energy. The project will develop techniques to deliver quantitative fluid typing, producible porosity, pore sizes and permeability measurements for shale samples, which could be used in the shale gas and oil industry. These techniques will improve the predictability of shale field developments that better inform their economic and environmental impact.

High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will us ....High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will use a proven high resolution optical technique to deliver new insight into solid nucleation and growth kinetics in the high-pressure cryogenic fluids that govern industrial blockage risk. The results will enable energy optimisation to increase liquefaction efficiency as well as tests of innovative blockage-remediation methods.Read moreRead less

Controlling hydrate slurry flow to enable deepwater oil and gas production. This project aims to investigate the plugging of hydrate slurries in pipelines to determine under what conditions they will flow satisfactorily without forming a blockage.

This project aims to investigate the plugging of hydrate slurries in pipelines to determine under what conditions they will flow satisfactorily without forming a blockage. Hydrate blockages are expensive and hazardous occurrences in oil and gas operations, so current prevention systems aim to avoid hydrate formation altogether through over-design. These over-designed hydrate prevention systems are extremely expensive to build and costly to run during the operations phase. The project intends to examine the behaviour of hydrate slurry flow as a function of the oil's properties, amount of water and degree of turbulence. Outcomes are intended to be a sophisticated approach to avoiding hydrate blockages that is safe but more efficient and less costly.Read moreRead less
